The Maximum Series Bubble Panel is a simple activity panel with a large circular window in the middle. It is a great physical barrier for blocking off tall ledges. Because of this, it is an excellent panel to include in higher areas of a play system. A completed playground should have no empty spaces at the edges of any of its deck platforms that are not occupied by slides, climbers, and activity panels. The Maximum Series Bubble Panel has no protrusions or features that would allow kids to climb it, and the large window also discourages children from trying to, since they will already be able to see to the other side. The transparent plastic window curves outwards, so that kids can lean into it and get a more complete view of their surroundings, while feeling as though they are floating above the playground inside of a giant bubble.
